Flab condom

Means a male or transgender female with over 20 stone of fat has a constant dropping peice of fat from their stomach over their penis acting as a flab condom,
There is a negative however as people with a flan condom can run too fast and have constant orgasms from their penis rubbing off the flab condom

“Is the 100 metre hurting you that bad that you have to keep moaning”
“Nah bro it’s a flab condom
